LOCKING TECHNOLOGY OF HEAT-INSULATING MATERIAL FOR SEAMLESS WELDING OF CONNECTING LOCKS Russian patent published in 2018 - IPC E04B1/78 E04B1/76 

FIELD: construction.

SUBSTANCE: invention relates to construction industry, in particular to the installation of external and/or internal insulation of various construction sites using Tepofol®, a heat-insulating material. Locking technology of seamless welding of connecting locks of heat-insulating material, the size of which varies from 10 to 250 mm, includes two layers of roll insulation, consisting of non-cross-linked polyethylene foam (non-cross-linked PE foam) and heat-reflecting coating, the surfaces of which are glued together with a heat gun by heating the surfaces to be glued to a temperature of 110–120 °C to achieve an integral, pressure-tight, seamless, heat-insulating web, fully formed from the roll insulation of non-cross-linked PE foam. Connecting locks are cut in two ways: directly during the production process of insulation, becoming in that case an integral element of the finished product, or at the time of installation work on the site when an additional locking connection is required to comply with the installation conditions.

EFFECT: invention allows to increase the energy efficiency of the facilities in the subsequent long-term operation, to reduce the labor costs and the costs of carrying out repair and insulation works during the installation of the thermal insulation Tepofol® due to simple and easy technology of installation and welding of locking systems.
